To all whom it may concern: 4

Be it known that I, Benet." M. W. HANSON, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Steady- Rests', of which the following is a specification.

This invention relates to steady rests.

A steady rest comprising my invention is susceptible of advantageous use in many diilerent connections. As an illustration I might mention that it can be employed with utility in conjunction with a metal-reducing machine. An apparatus of the latter type comprehends work-supporting means and the steady-rest can be employed for holding detail certain forms ofembodiment of the in vention which to enable those skilled in the art to ractice the same will be set forth in detail in the following description while the novelty of the invention will be included in theclaims succeeding said description.

Referring to said drawings, Figure l is a side elevation of a work rest and its associated means involving my invention, and Fig. 2 is a similar view of another form of the same. a

Referring first to Fig. 1. The numeral 2 denotes a slide which may be mounted for movement longitudinally of the bed of a metal-reducing machine. In practice this slide 2 has means cooperative therewith l'or clamping the same in an adjusted position on said bed, which as will be understood is not shown. Said clamping means, however is illustrated, being designated in a general way by 3. The slide 2 is represented as su porting a slide as 4 which moves transverse its adjustment may be effected by a nut on a l the screw 11, the movement of the carrier or screw as 5. I have described briefly two slides whichare common in certain classes oi metal reducing machines. It will be chvioils that lmay use my improvements with these slides or in any other waythat they canvbe. On the upper slide 4, there is a standard or post as 6 which constitutes, a convenient support for a lever as 7, the latter being represented as so pivoted to the standard or post as to present a short inner arm and a long outer arm. The upper portion of the standarr'l or post is illustrated projected outward and upward for a purpose that will hereinafter appear, and the function of said lever will be also reierred to hereinafter. The slide l has one or more guide projections or pins as 8 which are represented as standing at an upward and inward angle,

and said pin or pins cooperate with the block 9 which is perforated for thcpassage of said pin or pins the latter being rigid 3* connected in some suitable manner with said slide 4. f. be clear therefore that he block 9 has an upward and inward angular path. Said block constitutes a simple carrier for a steady-rest such as that dcnoted in a general way by 10, the steady rest and its carrier being ordinarily separably connected and the steady-rest being preferably rigidly mounted upon said carrier. This, however, does not "concern the present invention nor is it necessary tnal l employ a I steady-rest andv carrier of any particular form, the invention residing in the means for advancing the steadyu'cst the diameter oi the stock or work induced, assuming that said steady-rest be employed in a grimlingmachine. i should also s that the steady rest is so related wit work that the grinding tool can traw work for its entire length it necessary and can also operate on the work opposite the steady rest ich would not be the case were the work surrounded by a holding dcvire or similar means. l have illustrated as tapped through i carrier or block 9, aserew 11, constituti sim )le form otadjustable stop the inner end of the screw being cngageable by tne lever 7, It will be apparent that when the long arm 13' said lever is swung downward, the short arm. thereof will be raised, and said short arm being in contact with the tip or inne block 9 and the steady rest 10 will follow, the- As one feature of the invention I combine with a steady rest, means'involving an automatically-o erative cam, for unyieldingly and prefera ly bodily advancing said steady rest and along what is in the present case a straight path. If desired the same may operate against the lever 7. There are other ways of obtaining the cam action and one of them will be hereinafter described. So also the cam maybe operated in any suitable way certainty of action, however, can be secured by the use of a weight.

Referring to Fig. 1 it will be seen that the outer end of the support 6 has a bearing as 12 for the cam-lever 13, the active face of the cam-portion of said lever being preferabl exterior thereof and directly cooperative with the long outer arm of the lever 7. The camlever 13 is provided with an adjustableweigh't as 14, whlch may be held in a desired adjusted position by a set-screw as 15 tapped through the weight and engaging the camlever 13. Said cam lever exerclses a constant downward thrust onthe long outer arm of the lever 7 whereby the action hereinbefore described can be accom lished.

I prefer to so mount the camever 13 that the distance between the point en aged by the active portion of the cam 16 an' the axis of motion of said cam-lever is so very much less than that between said axis and the lace at which the operating power or weight is applied to said camlever, that it is practically im ossible to cause a backward movement 0 said cam-lever by force ap lied thereto at anypoint between its axis an the work. If desired the axially-movable cam may be located in a cut-away portion 17 in the extreme outer end ofthe lever 7.

I may if desired and as shown, pivotally connect to the standard 6 the lower end of a serew as 18, said screw extending upward and inward at an angle and throu h a hole or perforation in the carrier or bloc 9, and having-a nut as 19 constituting a limiting stop for the said block or carrier. I The stroke of the block or carrier 9 can be regulated by the adjustment of the screw 11 and when the advancing movement of said carrier is completed it will abut against the nut 19.

If desired and as illustrated in Fig. 2 the cam need not act against a lever such as 7 shown in Fig. 1. directly against the block or carrier 9 or against an element such as the screw 11 forming a part of the same. With these excep- In Fig. 2 the cam acts' tions all the pFarts afppearin in Fig. 1 are reproduced in ig. 2 or'whic reason corres onding'characters will be ap lied to the (uplicated parts. shown as pivotally supported by the standard 6, its cam 16 acting against the inner end of the screw 11 precisely as hereinbefore described. The cam-lever 13 has an adjustable weight 14. Said cam-lever 13 is so mounted as to obtain the functions hereinbefore alluded to.

Except in the particulars noted the two forms .0 the device are the same and in both I said forms the steady-rest carrier is advanced steadily and automatically by a powerful thrust although it is unyieldingly held against backward or retractive motion.

In both forms of the cam devices the active faces thereof in addition to being as hereinbefore set.forth exterior thereof are also preferably .of progressively increasing radius by reason of which I can obtain the maximum effect thereof and in addition to this important feature the thrust applied to the steady-rest carrier occurs referably at a sin le point and also prefera ly at one side of t e steady-restin view of which the grinding tool can traverse the work from end to end thereof without coming in contact with any part of the steady-rest or its adjuncts, the same applying when the work is moved longitudinally and relatively to the carrier.

What I claim is:

1. The combination of a steady-rest, a carrier for said steady-rest upon which the latter is removably, rigidly mounted, and means for automatically advancing said carrier, said means involving a cam cooperative with and for a plying its effect to the carrier to unyielding y prevent retractive movement thereof.

2. The combination of a steady-rest carrier having an adjustable stop, and means acting against said adjustable stop to automatically advance the carrier, said means involving a cam cooperative with and for 'a plying its effect to said stop and thereby -t e carrier to unyieldingly prevent retractive movement thereof.

'3. The combination of a steady-rest carrier, a screw adjustably carried by said carrier, and automatically-operative means act ing against said screw to advance the carrier, sald means involving a cam cooperative with and for applying its effect to said screw and thereby to the carrier to unyieldingly prevent retractive movementof the latter.

4. The combination of a steady-rest car rier, a guide pin fixed with respect to the The camever 13 is erative with and for applying its effect to the carrier to unyieldingly prevent retractive movement .thereof.

-5. The combination of a steady-rest carrier, and means for automatically advancing the same, said means involving a cam cooperative with and for applying its effect to the carrier for unyieldingly preventing retractive movement thereof and the active face of the cam being curved and of progressivelyincreasing radius.

6. The combination of a steady-rest carrier, an automatically operative cam, and a movable device interposed between the automatically operative cam and the carrier, for transferring the effect of the cam to the carrier to advance and unyieldingly prevent retractive movement of said carrier.

7. The combination of a steady-rest-carrier, an automatically operable cam, and a pivotally mounted lever supported independently of the cam and located between said cam and carrier for transferring the effect of the cam to the carrier to advance and unyieldingly prevent retractive movement thereof.

8. The combination of a steady-rest car: rier, an automatically operative cam-lever;

and a movable device interposed between said cam .lever and the carrier, for transfer-ring the effect of the cam portion of said lever to said carrier to advance and unyieldingly prevent retractive movement of the latter.

9. The combination of a steady-rest carrier, a lever active against the same, and a weighted cam-lever operative against the first mentioned lever and serving to actuate the latter to advance and unyieldi: gly prevent retractive movement of said carrier.

10. The combination of a steady-rest carrier, means for automatically advancing the same, comprising a cam cooperative with and for applying its effect to said carrier to unyieldingly prevent retractive movement thereof, and means for limiting the advancing.

movement of said carrier.

11. The combination of a steady-rest carrier, and means for automatically advancing the same, said means in xolving a cam cooperative with and for applying its effect to said carrier to unyieldingly prevent retractive movement thereof, the carrier advancing effect being applied to said carrier at b ut a single oint t ereof.

-].2. The combination of a steady-rest, a carrier for said steady-rest, and means for automatically advancing said carrier by a thrust applied thereto at one side of the steady-rest said means involving a cam which acts against the carrier to unyieldingly prevent retractive movement thereof.

13. The combination of a steady rest adapted to engage the .Work and to permit the operation of a tool opposite said steady-rest, a carrier rigidly carrying said steady rest, and cam means for automatically advancing said carrier and for unyieldingly preventing retractive movement thereof.

In testimony whereof I affix my signature in presence of two witnesses.
